Microsoft has changed the estimated useful life of its data centers and office buildings from 15 years to 25 years, an accounting move that will shift some future data-center leases out of reported capital expenditures as the company funds its AI expansion.
PYMNTS first highlighted the change following Microsoft’s fiscal 2026 fourth-quarter results, while CFO Amy Hood detailed it during the company’s July 29 earnings call. The adjustment takes effect at the start of fiscal 2027 and does not mean Microsoft is slowing its construction of cloud capacity—or that servers and GPUs will remain in service for 25 years.
Microsoft reported quarterly capital expenditures of $41 billion, up 70% year over year, as it added capacity for Azure, Microsoft 365 Copilot and other AI services. The company said roughly two-thirds of recent capex was directed to short-lived assets, primarily CPUs and GPUs, which operate on a much faster replacement cycle than buildings and data-center infrastructure.

Microsoft now expects approximately $175 billion in calendar-year 2026 capex, but Hood said that figure reflects the useful-life revision. More future leases will be classified as operating leases rather than finance leases; finance leases are counted in Microsoft’s capex figure, while operating leases are not.
That distinction is important for investors and IT buyers trying to interpret Microsoft’s infrastructure spending. Cash commitments and demand for capacity do not disappear because a lease is classified differently. The presentation of the investment changes, while Microsoft’s underlying obligation to secure sites, power, cooling and compute remains.
Microsoft also said its investment expectation, excluding the lease-classification effect, remains unchanged. It expects fiscal 2027 capex to rise year over year.

Azure Demand Still Sets the Pace​

The financial results underline why Microsoft is still expanding aggressively. Intelligent Cloud revenue reached $39.3 billion for the April-to-June quarter, up 32% year over year, while the company said Azure revenue surpassed $100 billion annually for the first time.
CEO Satya Nadella also said Microsoft 365 Copilot exceeded 30 million paid seats. Microsoft’s own outlook says it expects to remain capacity-constrained through 2026, even as it brings more GPU, CPU and storage capacity online.
For enterprise customers, the immediate takeaway is not a pricing or service change. It is a signal that Microsoft is trying to make its AI infrastructure buildout more financially predictable while continuing to add capacity. The practical test will be whether those additions reduce Azure availability constraints and support sustained performance as Copilot and Azure AI workloads grow.
